CLOSET TANK.

Application filed June 17, 1925.

To all whom t 'may concer/n.'

Be it known that l, Roen'n'ro HcrDarcr-r r MARTINEZ, citizen ot theRepublic otl Cuba., residing at Habana, Cuba, have invented certain newand useful Improvements in Closet Tanks, or which the following is aspecitication.

This invention refers to closet tanks and especially 'to closet tanks otthe lower type, although said invention can be applied to tanks of thehigh type with slight modilications without atecting the essential idea`o1" the invention, and has for its main object the providing of amodification in the construction ot tanks ot this kind which avoidsjoints, packing etc. and makes the discharging of same take place bymechanical means when wished, emptying the tank totally and avoidingleaks or continued loss of water and also the frequent and untimelydischarge ot the tank which is caused by detects in the valvular systemof same.

More advantages and other considerations pertaining toI this inventionwill be known in the course ot this specication, especially by thoseexperts in the art to which same pertains and by the aid of the figuresin the attached drawings in which the same character et referencedesignate the same parts.

In the drawings:

Figure 1 is an upper plan view of a closet and closet tank constructedin accordance with this invention.

Figure 2 is a longitudinal vertical section according to lines 2-2 ofFigure 1.

Figure 3 is a partial sectional view in detail of the tank showing bydotted lines a working position of the parts.

Figures 4 and 5 are detailed views, partial and in perspective of thecooperating parts of the tank.

In the drawings is shown by #1, a closet tank of any approvedconstruction, which rearwardly presents an opening 2 into which projectsthe upper end of the shortest branch 3 of a trap the longest branch l ofwhich is connected at its upper end to a pipe 5 connected to a boredopening in the bottom ot the tank 6. A

r1`he pipe 5 in its upper end is connected to a device as is shown indetail in Fig. 4L

' of the drawings and consists of a funnel 7 which terminates lowerly ina threaded neck 8 to be screwed to the upper end ot the pipe V andscrewed outerly on this neck to the tank o is a washer 9 whichcooperates with Serial No. 37,829.

a plate 9 integral with the funnel forming a water tight seal.

From the plate 9 extend in diametrically opposite directions, an arm 10ending in an enlargement with an eyelet 10 and a supporting member 11which ends in a seating plate 11. On the end of the arm 10 is pivoted asemi-spherical bell 12 provided for this purpose with hanging ears 12which presents bores 12 registering with the bore 10 through which ispassed a pin 13, and the bell 12 bearing upon the plate 11 in theclosing position shown in Fig. 2, and having near its edges a pluralityof spaced bores 111, the object of which will be eX- plained furtheralong.

From the body of the bell 12, projects outwardly two ears 12 betweenwhich is pivoted the lower end of a rod 15 and connected on its upperend is an angular lever 16 mounted through a. hub 17 which passesthrough the front wall of the tank 6 and said lever ending outerly in ahandle 18 for operating same.

Numeral 19 designates the pipe through which the waterl flows into thetank 6.

The operation ci this tank is as explained below.

Supposing the tank 6 to be lled with water and the bell 12 bearing uponthe support 11 of the part 11 and the trap 3--4 lilled, that is with itsbranches 3 and 4 lilled with water, all as shown in Figures 2 and 3.

Under these conditions the air into the bell 12 and filling the pipe 5will form a pneumatic closing, preventing the water contailnpd in thetank from entering the funne But if the handle 18 is operated causingthe rod 15 to be pushed upwardly, this will drag the bell 12 along andraising same as indicated by dotted lines in Fig. 3, the water will llowinto the funnel 7 and form a continuous current in the trap 3 4discharging into the tank 1 through the opening 2 and which current willcontinue even when the bell is allowed to drop, when ceasing to operatethe handle 18, and discharging all the water contained in the tank 6.

While the tank is being refilled, the water when descending under thebores 14 in the bell 12 will leave them uncovered and ot' course, thevacuum under the bell will be broken and the bell will till with air.The bores 14; will be hydraulically closed when the level of the Waterwhich flows through pipe lQViHtO-vthetank rises, causing the`- pneumaticclosure Whcliepirevents. thewater which 'fills the tanl; from owing intothe funnel'.

Having thus fully described. the invention, what is claimed is:

A flush tank mechanism comprising in combination with a tank, a pipeextending upwardly in and terminating sli-'gl'it'ly above, the bottom ofthe tank and having au eX- pandfi-ng open upper end', a hinged plainhemispherical bell for covering the open upper end ofthe pipe;- andmeans7 arranged within the; tank` and operable fromoutside the tank, toIraise the bellen its hinge, a series` of perfoiiat'ons in the belli and'above the lower edge thereof, a support integral with and, projectingfrom. the pipe, ears on the support for li'ngedly receiving the bell,and a.,- shelf on the support to receive the edge of the bell when it isin its lowered position and' screw threads on the pipe for connecting itto the tank.

In testimony whereof I have signed my name to this specification.
